I think being able to choose the bonus you will use of earned bonuses would be great...I mean you finish the 3rd combat evolution...why would you need the scouting and combat speed boost if that was the last boost of that type and you need another type of bonus to help you.
A button or toggle for each resource in the port to auto sell would be wonderful. Especially for something like food that has no use once you buy all the city upgrades with food.
